Doctors (MDs and DOs), nurse practitioners, and physician assistants can authorize medical marijuana in most states with legal programs. However, no healthcare provider in the United States actually “prescribes” marijuana in the traditional sense. Because cannabis remains a Schedule I controlled substance at the federal level, providers instead issue a recommendation or certification that allows you to apply for a state medical marijuana card.
Why It’s a Recommendation, Not a Prescription
The distinction matters. A prescription is a specific instruction for a pharmacist to dispense a federally approved medication. The FDA has not approved whole-plant marijuana as a medicine, and as a Schedule I substance, it cannot move through the standard pharmacy system. What providers in legal states do instead is certify that you have a qualifying medical condition and that cannabis may benefit you. This certification is the document you bring to a state program to get your medical marijuana card.
This legal workaround exists because state medical marijuana laws operate independently of federal drug scheduling. States allow licensed providers to recommend cannabis without violating federal law, since a recommendation is protected speech rather than a controlled substance prescription.
Which Providers Can Certify You
The specific provider types vary by state, but the most common categories are:
- Medical doctors (MDs) and doctors of osteopathy (DOs) are eligible in every state with a medical program.
- Nurse practitioners (NPs) can certify patients in a growing number of states. Virginia, for example, authorizes advanced practice registered nurses who hold joint licensure from the Board of Medicine and the Board of Nursing.
- Physician assistants (PAs) are similarly authorized in many states, including Virginia, where PAs licensed by the Board of Medicine can issue written certifications.
Some states restrict certification authority to MDs and DOs only, while others have expanded access to include NPs and PAs. A handful of states also allow naturopathic doctors or podiatrists for conditions within their scope of practice. Your state’s medical marijuana program website will list exactly which provider types are accepted.
One Major Exception: VA Doctors Cannot Help
If you receive care through the Veterans Health Administration, your VA provider cannot recommend medical marijuana, help you obtain it, or even fill out the paperwork for a state program. This applies regardless of which state you live in. VA clinicians are federal employees bound by federal drug scheduling, and they may only prescribe FDA-approved medications. Veterans who want medical marijuana need to see a separate, non-VA provider for their certification. Your VA treatment will not be affected by participating in a state cannabis program, but the VA system itself cannot be part of the process.
What Providers Must Do Before Certifying
A doctor can’t simply decide to start recommending cannabis. Most states require providers to register with the state’s medical marijuana program and complete specialized training. Oklahoma, for instance, is implementing a requirement starting January 2026 that physicians complete cannabis-specific continuing medical education (typically 3 to 6 hours of coursework) and formally register with the Oklahoma Medical Marijuana Authority before issuing any recommendations. Courses cost between $95 and $199 and must be renewed annually.
Many states also require that the certifying provider have an established patient relationship with you, not just a one-time visit. This means the provider needs access to your medical records and must conduct a genuine evaluation of your condition. Some states specify a minimum length of the patient-provider relationship, such as 90 days, before a certification can be issued.
Conditions That Qualify
Each state maintains its own list of qualifying conditions. While the specifics differ, certain diagnoses appear across nearly every program: cancer (particularly when treatment causes severe nausea or wasting), epilepsy and seizure disorders, multiple sclerosis, Crohn’s disease, PTSD, chronic or intractable pain, Parkinson’s disease, and ALS. Some states also include conditions like sickle cell disease, Tourette’s syndrome, autism spectrum disorder, and peripheral neuropathy.
A few states, like Oklahoma, have historically allowed providers to recommend cannabis for any condition they deem appropriate, without a fixed qualifying list. Others, like Georgia, are far more restrictive, limiting their program to specific diagnoses that must often be classified as severe or end-stage. Checking your state’s program is essential, because a condition that qualifies in one state may not qualify next door.
How the Process Works
Getting a medical marijuana card follows a fairly standard sequence across most states. Massachusetts lays it out in four steps that are typical of most programs. First, you visit a provider who is registered with the state as a certifying practitioner. During that visit, the provider reviews your medical history, confirms your qualifying condition, and issues a written certification along with a PIN or registration number.
Next, you apply online through your state’s medical marijuana program, using the PIN from your provider and a valid government-issued ID proving state residency. If approved, most states let you print a temporary card immediately so you can purchase from a licensed dispensary while your physical card arrives in the mail, usually within one to three weeks.
Certifications typically expire after one year, meaning you’ll need an annual follow-up visit with your provider to maintain your card.
Federal Rescheduling Could Change Everything
The landscape may shift significantly in the near future. In 2023, the Department of Health and Human Services recommended moving marijuana from Schedule I to Schedule III under the Controlled Substances Act. The Department of Justice issued a proposed rule in May 2024, which received nearly 43,000 public comments and is currently awaiting an administrative law hearing. In December 2025, a White House executive order directed the Attorney General to complete this rescheduling process as quickly as possible.
If marijuana moves to Schedule III, it would join substances like testosterone and certain codeine formulations that doctors can prescribe through standard channels. This could eventually allow traditional prescriptions, open the door to FDA-approved cannabis products, and potentially change the rules for VA providers. More than 30,000 licensed healthcare practitioners across 43 U.S. jurisdictions currently recommend cannabis for over 6 million registered patients. Rescheduling would reshape how all of them interact with the system, though the exact timeline and practical effects remain uncertain while the rulemaking process plays out.
